Abstract
A movable guard for safeguarding a machine, comprising: a protective cover for covering a working area of the machine; a counterweight; a connecting element for connecting the protective cover to the counterweight; a deflection element, which is configured to deflect the connecting element in such a way that the protective cover and the counterweight are movable in mutually opposite directions; and a drive, which acts on the counterweight in order to drive the counterweight.
Claims19
A movable guard for safeguarding a machine, comprising:
- a protective cover which is configured to cover a working area of the machine;
- a counterweight;
- a connecting element which connects the protective cover to the counterweight,
- wherein the connecting element comprises a first cable, the ends of which are connected to each other, and a second cable, the ends of which are connected to each other, and wherein the first cable and the second cable are spaced apart, run parallel to each other and are each connected separately to the counterweight and the protective cover;
- a deflection element which is configured to deflect the connecting element in such a way that the protective cover and the counterweight are movable in mutually opposite directions, wherein the deflection element comprises two first deflection pulleys for deflecting the first cable and two second deflection pulleys for deflecting the second cable;
- and
- a drive which acts on the counterweight in order to drive the counterweight, wherein the drive engages on the counterweight at a force input point which is arranged at a same distance from the first and the second cable.
A movable guard for safeguarding a machine, comprising:
- a protective cover which is configured to cover a working area of the machine;
- a counterweight;
- a connecting element which connects the protective cover to the counterweight;
- a deflection element which is configured to deflect the connecting element in such a way that the protective cover and the counterweight are movable in mutually opposite directions;
- and
- a drive which acts on the counterweight in order to drive the counterweight, wherein the drive is connected to the counterweight by means of a magnetic coupling.
A movable guard for safeguarding a machine, comprising:
- a protective cover which is configured to cover a working area of the machine;
- a counterweight;
- a connecting element which connects the protective cover to the counterweight;
- a deflection element which is configured to deflect the connecting element in such a way that the protective cover and the counterweight are movable in mutually opposite directions;
- and
- a drive which acts on the counterweight in order to drive the counterweight, wherein the drive comprises a linear drive, wherein the linear drive comprises a slider which is moved in translatory manner, and wherein the slider and the counterweight together have a total dead weight which differs by no more than 10% from a dead weight of the protective cover.
A movable guard for safeguarding a machine, comprising:
- a protective cover which is configured to cover a working area of the machine, wherein the protective cover has a substantially U-shaped cross section;
- a counterweight;
- a connecting element which connects the protective cover to the counterweight;
- a deflection element which is configured to deflect the connecting element in such a way that the protective cover and the counterweight are movable in mutually opposite directions;
- and
- a drive which acts on the counterweight in order to drive the counterweight.
